Multiple kinases regulating NF-κB and STAT3 signaling (NF-κB/STAT3 kinases)

Multiple kinases regulating NF-κB and STAT3 signaling refers to a functional group of signaling enzymes that coordinately control the activation of two pivotal transcription factors: Nuclear Factor kappa B (NF-κB) and Signal Transducer and Activator of Transcription 3 (STAT3). This group primarily includes Janus kinases (JAK1, JAK2, JAK3, TYK2), IκB kinases (IKKα, IKKβ, IKKε), and non-receptor tyrosine kinases such as Src and TBK1. These pathways are central to the regulation of inflammation, immune responses, and cell survival, and they exhibit significant cross-talk, often forming a feed-forward loop that sustains chronic inflammation and oncogenesis. In many pathological states, particularly in various cancers and autoimmune disorders, these kinases are constitutively active, leading to the overexpression of genes involved in tumor growth, metastasis, and resistance to apoptosis. Therapeutic strategies targeting these multiple kinases aim to simultaneously inhibit both NF-κB and STAT3 pathways to overcome the redundancy and compensatory mechanisms that often lead to resistance with single-pathway inhibitors. Drugs like momelotinib and various multi-kinase inhibitors are designed to hit these nodes, providing a broader anti-inflammatory and anti-tumor effect.
